For lvling basically you want AP and Stam. The scales are more for cap level characters for gear comparison. The scale can be used as is once u reach 65ish. Before that there isn't much point in it, because you change gear so often up to that point.

These are just starting points too. You have to use the simulator to figure out your custom EP. The values change with stats and gear. If you are at hit cap then hit is no longer as important as it was, and the simulatoe will show the change in stat weights. http://elitistjerks.com/f79/t31667-enhsim_dps_simulator/ is a good place to start, and look it was in the first post on the page. Imagine that. Read the read me or be confused beyond reason. This sim will give you strings that you can plug into Pawn as well as a few others. It does not generate gem slot values. But once you run it then use pawn to find the values of the gems you are going to put in the slots and then you have a value for your slots. As soon as I can log in after the patch I will post the values I got from the sim and the gem values aswell. Run it. Love it. Or suck at dps.
